Alcohol and the Appetite

Options
Hi! I recently went to Vegas and of course consumed alcohol. Before that, I was on and still am trying to maintain a 1200 calorie diet as prescribed by my doctor. Since drinking, I only drank one night and a little the next day, I have had an insatiable appetite! I cannot seem to get full. Though I am not craving fatty foods, I am craving the satisfaction of being full. I have tried increasing my calorie intake to 1300-1500 calories but even then I am still hungry. I think one day I ate close to 3500 calories and it barely made a dent. As a result, I haven't lossed any weight :(

Has this happened to anyone before? If so why is this? And or advice? I would think that an increased appetite due to alcohol wouldn't last this long. Hmmm...
